JOURNAL-BEARING FOR CULTIVATOR-DISKS.

Application filed October 30, 1913.

To all whom it may concern:

Be it known that I, VVEsLEY A. PAUL, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in J ournal-Bearings for Cultivator-Disks, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to disk cultivators and particularly to the means employed in mounting the disks, and in adjusting them as may be desired.

The object of my invention is to simplify the mounting and adjusting of the disk on the cultivator without detracting in any way from the necessary strength of the assembled mechanism.

Referring to the drawings in which similar numerals indicate identical parts Figure 1 is a vertical section of a disk and its mounting, and Figs. 2, 3 and 4 are detail views.

The disk 1, of the usual cultivating type, is secured preferably by rivets, to a casting 2, the latter having an inner central projection 3 and an outer central projection 4 to form a hub in which is secured, by a pin or rivet 5 the outer end of a cylindrical spindle 6. The inner end of the spindle 6 has a collar 7 secured thereon; encircling the spindle 6 is a bushing 8 inclosed in a solid box 10 having an annulus 9 between which and the collar 7 the bushing 8 is secured. The annulus 9 is preferably integral with the box 10 and has on its inner side a lug 19 which is adapted to engage with a notch 20 in the bushing 8 to prevent the latter from turning.

The central projection 3 extending through the disk 1 is seated in the end of the box 10 against the annulus 9 and has below it in the rim of the box 10 a cutaway space 21 through which dirt and grit, liable to accumulate during the operation of the disk, can readily escape.

A support 12 forming part of a cultivator has mounted upon it a bracket 13 having a Specification of Letters Patent.

Serial No. 798,357.

circular radially serrated base 14 which is adapted to engage with a similarly serrated circular plate 15 preferably integral with the box 10. The box 10 being at an angle and the plate 15 horizontally disposed, a recess 16 isformed; a bolt 17 passes through the plate 15 and the base 14 holding them securely together, the head of the bolt 17 being in the recess 16. A slot 18 extends from the center outwardly of the plate 15 and above the recess 16; it will be readily seen that by reason of said slot 18 and recess 16 the detachment of the disk mounting can be quickly and easily effected by loosening the bolt 17 until the serrations on the base 14 and the plate 15 are disengaged when the disk mounting can be readily withdrawn, or if adjustment of the disk to a different angle for cultivating is desired, the plate 15 can be turned until the required adjust ment is obtained when the plate 15 and base 14 are again clamped together by tightening the bolt 17 and engaging the serrations on the plate 15 and the base 14.

The inner end of the box 10 is threaded and fitted with a cap 22 which is readily detached for the purpose of applying a lubricant or for removing the collar 7 and bushing 8.

What I claim is- 1. A ournal bearing comprising a spindle having a collar on one end thereof, a rotary member on the opposite end of the spindle, a box in which the spindle is journaled, an annulus in the outer end of said box, a bushing encircling the spindle between the collar and said annulus, and a lug integral with the annulus to engage with a notch in the adjacent end of the bushing to prevent rotary movement of the latter.

2. A j ournaled bearing comprising a spindle, a box having open ends, a cap to close one end of the box, an annulus in the opposite end of the box, a collar on the spindle adjacent the cap, a bushing between the spindle and box, and a rotary member secured on the spindle.

3. A journaled bearing comprising a spin die, a one piece boX having both ends open In testimony whereof I afiix my signature, and a cap to close one end thereof, an annuin presence of two witnesses.

lus in the opposite end of the box, a collar on the spindle adjacent the cap, a one piece WESLEY U bushing within the box and between the Witnesses:

collar and annulus, and a rotary member BERTIAIA A. MAURER,

secured on the spindle. JESSIE L. SIMSER.
